This paper aims to implement current model predictive control in a multilevel converter supported by solar photovoltaic (SPV) system for a grid-connected application that improves power quality. For this purpose, a three-level neural-point-clamped Inverter (NPC) topology is chosen as a shunt active power filter (SAPF). The reference signal for the SAPF is obtained from the instantaneous power theory, based on Cross-Vector theory. these reference currents are used to generate a gate signal for the SAPF. Furthermore, this study presents the application of a Particle Swarm Optimization (PSO) maximum power point tracking (MPPT) technique to the DC-DC boost converter, aiming to obtain the highest possible power from the photovoltaic array. The simulation results validated the feasibility of the proposed APF.
